The association between an energy-adjusted dietary inflammatory index and inflammation in rural and urban Black South Africans

Objective: To quantify the inflammatory potential of the diet of rural and urban Black South Africans using an adapted energy-adjusted dietary inflammatory index (AE-DII) and to investigate its relationship with inflammatory and cardio-metabolic disease risk markers. Dietary inflammatory potential has not been investigated in African populations. Design: Cross-sectional investigation. Setting: Rural and urban sites in the North West province of South Africa. Participants: 1,885 randomly selected, apparently healthy Black South Africans older than 30 years. Results: AE-DII scores ranged from –3.71 to +5.08 with a mean of +0.37. AE-DII scores were significantly higher in men (0.47±1.19) than in women (0.32±1.29), and in rural (0.55±1.29) than urban participants (0.21±1.19). Apart from its dietary constituents, AE-DII scores primarily associated with age, rural-urban status and education. Contrary to the literature, alcohol consumption was positively associated with AE-DII scores. Of the four tested inflammatory and 13 cardio-metabolic biomarkers, the AE-DII was only significantly negatively associated with albumin and high-density lipoprotein cholesterol, and positively with waist circumference and fasting glucose, upon full adjustment. Conclusion: Rural men consumed the most pro-inflammatory diet, and urban women the least pro-inflammatory diet. The diet of the participants was not overtly pro- or anti-inflammatory and was not associated with measured inflammatory markers. The inflammatory potential of alcohol at different levels of intake requires further research. Understanding dietary inflammatory potential in the context of food insecurity, unhealthy lifestyle practices and lack of dietary variety remains limited.

Is Transition from Secondary to Tertiary Education Less Likely among Black South Africans than their Non-Black Counterparts in the Democratic Dispensation?

Education provides the building blocks for skills development for acountry’s labour market. Investment in education is hence an importantdeterminant of economic growth and has been associated with various economicbenefits. However, non-transition to tertiary education is a common phenomenon.This study examined the probability of a specified age cohort transiting to tertiaryeducation in South Africa and compared Black South Africans with otherpopulation groups considering environmental and individual factors. Usingcross-sectional data from the 2016 South African Community Survey, the studyrevealed that the difference in the probability of transition to tertiary educationbetween Whites and Blacks was not statistically significant. The findings will beuseful to policymakers in formulating strategies to improve the quality of thelabour market, and thus South Africa’s economic competitiveness.Key words: Transition to tertiary education, South African education system,apartheid education, post-apartheid education, economic development

Population-specific diversity of the immunoglobulin constant heavy G chain (IGHG) genes

Human immunoglobulin G (IgG) molecules, IgG1, IgG2 and IgG3, exhibit substantial inter-individual variation in their constant heavy chain regions, as discovered by serological methods. This polymorphism is encoded by the IGHG1, IGHG2, and IGHG3 genes and may influence antibody function. We sequenced the coding fragments of these genes in 95 European Americans, 94 African Americans, and 94 Black South Africans. Striking differences were observed between the population groups, including extremely low amino acid sequence variation in IGHG1 among South Africans, and higher IGHG2 and IGHG3 diversity in individuals of African descent compared to individuals of European descent. Molecular definition of the loci illustrates a greater level of allelic polymorphism than previously described, including the presence of common IGHG2 and IGHG3 variants that were indistinguishable serologically. Comparison of our data with the 1000 Genome Project sequences indicates overall agreement between the datasets, although some inaccuracies in the 1000 Genomes Project are likely. These data represent the most comprehensive analysis of IGHG polymorphisms across major populations, which can now be applied to deciphering their functional impact.

Counter-narratives of achievement at South Africa's first apartheid-era black medical school, 1950s to the early 1990s

This article examines the construction and dissemination of two particular achievement narratives - one focused on high academic standards, the other on a Black Consciousness-inspired "Black pride" - that were produced by academic staff and students at the University of Natal's Medical School, South Africa's first apartheid-era black medical school in the highly racialised context of the 1950s to early 1990s. While quite different in terms of their producers and periods of origin, the article argues that both these narratives developed with a similar purpose: as counter-narratives, which intended to critique or challenge the pervasive and disparaging apartheid-era discourse that portrayed black South Africans as inferior. Indeed, both these narratives sought, in their own respective ways, to enable those producing them to reframe the dominant apartheid discourse, to offer alternatives, including more positive views about black South Africans, and to take an oppositional stance. Yet, while both developed as counter-narratives, they did so with different emphases and stances taken to challenge apartheid, highlighting the complexity of these narratives. In addition, this article examines how both these narratives could sometimes, in particular historical moments, overlap in time and even amalgamate, leading to the construction of hybridised narratives.

Unravelling the makings for entrepreneurial success: A case study of the Maponya business in South Africa

Background: The achievement of local entrepreneurial success in South Africa is projected to reduce widespread unemployment in the townships, enhance the general buying power and upraise the overall productivity and living standards of poor South Africans. However, most entrepreneurial ventures do not survive for long, and remarkably the number of self-established, privately owned and long-standing businesses amongst black South Africans is very few.Aim: To investigate the factors that have led to the success and longevity of the Maponya business case.Setting: This research focused on a privately owned, self-initiated black South African successful business, which has been in existence for at least six decades.Methods: A qualitative research approach of a descriptive and explanatory single case study design was utilised using data from a semi-structured interview guide. Thematic and content analysis were used in the data analysis process.Results and findings: It was found that the Maponya business case is a family-controlled type of business. The success and longevity of the Maponya business case are attributable to the closeness of members within the Maponya family or clan. Access to membership is well controlled and requires adherence to a set of values based on one another to prosper in business.Conclusion: The documented findings can serve as a template for understanding the operationalisation of management techniques and leadership principles for entrepreneurial success and longevity in business for black South Africans and illuminate business prowess for the Southern African region and the entire African continent.

phenomenon of divorce and its challenge to the black African communities: A need for pastoral and indigenous African marital therapy

Divorce is a painful and traumatic experience that disrupt the lives of people. Research has shown that the phenomenon of divorce among black South Africans is escalating on a yearly basis. This is accompanied by both emotional, spiritual and psychological effects which impact on the well-being of people. Furthermore, divorce is understood as a disruption of normal life and it also threatens the stability and sustainability of social institutions. As the article is written from a context of pastoral care and counselling, it acknowledges the existence of other forms of care beyond the boundaries of the Christian ministry of healing. The indigenous African martial therapy plays a vital role in black African communities in strengthening marital bonds and its longevity. Even though this African model has been disrupted by the wave of industrialisation and urbanisation, the article argues that its methods of healing, counselling and mediatory role are necessary for African people and in response to the collapse of the institution of marriage.
